熱鍍鋅方管和冷鍍鋅方管的區別
鍍(du)(du)鋅(xin)(xin)方(fang)(fang)管(guan)(guan)是(shi)一種具以熱軋或冷(leng)軋鍍(du)(du)鋅(xin)(xin)帶鋼(gang)或鍍(du)(du)鋅(xin)(xin)卷板為坯料經冷(leng)彎(wan)曲加(jia)工(gong)(gong)成型后再經高頻(pin)焊接制成的(de)方(fang)(fang)形截面形狀尺寸(cun)的(de)空心方(fang)(fang)形的(de)截面型鋼(gang)鋼(gang)管(guan)(guan)，或將事先做好(hao)的(de)冷(leng)彎(wan)空心型鋼(gang)管(guan)(guan)再經熱浸鍍(du)(du)鋅(xin)(xin)加(jia)工(gong)(gong)而成的(de)鍍(du)(du)鋅(xin)(xin)方(fang)(fang)矩管(guan)(guan)。鍍(du)(du)鋅(xin)(xin)方(fang)(fang)管(guan)(guan)從生產工(gong)(gong)藝(yi)上是(shi)分為熱鍍(du)(du)鋅(xin)(xin)方(fang)(fang)管(guan)(guan)和冷(leng)鍍(du)(du)鋅(xin)(xin)方(fang)(fang)管(guan)(guan)的(de)。正是(shi)由于這兩種鍍(du)(du)鋅(xin)(xin)方(fang)(fang)管(guan)(guan)的(de)加(jia)工(gong)(gong)不(bu)相同(tong)也(ye)就造(zao)就了它(ta)們很多(duo)不(bu)同(tong)
